Неке Језичке Особености Његошевог ,,ГОРСКОГ ВИЈЕНЦА“

Since all the characters from The Mountain Wreath originated from simple folk, they had to speak (and do speak) as simple folk – is Popović’ dominant view on the language of Njegoš’ work. What is more, he indicated that the folk dialect is the most significant feature of the language of the Wreath, but there is something more that he presented using specifically chosen material in a particular chapter of the volume On the Mountain Wreath, and that is now Njegoš and his language indicates that he is much more than a simple folk author. We have, working with the material provided by Popovic, but also relying on overall insight into the entirety of The Mountain Wreath, analyzed several linguistic features: certain groups of consonants, the fate of the consonant f, moving vowels, system of pronouns, adjectival-pronoun forms, verbs, some syntactic features, etc. Our analyses have indicated that the dialectical note in Njegoš’ language is quite prominent; however, these features are never solely local (originating from the village Njeguši), but are instead always a part of a broader region. At the same time, the poet-author of The Mountain Wreath when choosing between the dialectological and literary character often selects the latter – thus, in constructing its idiosyncratic poetic language Njegoš relies on both the dialectical and literary form. The fact is that the language of The Mountain Wreath brings it closer to the work being done by Vuk and to his model of the literary language, at the same time distinguishes it from most of the Montenegrin dialects of the time. Pavle Popović considered his chapter on diction a “short and entertaining stroll through the Wreath”, while it turned out that it is much more than that. Our paper has, in addition to linguistic analyses, also provided a way back to Popović’ impressions and the revival of his views of the language of The Mountain Wreath, expressed at the beginning of the 20th century.
A QUADRATICALLY CONVERGENT ITERATIVE METHOD FOR NONLINEAR EQUATIONS
윤병인,Miodrag S. Petkovic 대한수학회 2011 대한수학회지 Vol.48 No.3
In this paper we propose a simple iterative method for nding a root of a nonlinear equation. It is shown that the new method, which does not require any derivatives, has a quadratic convergence order. In addition, one can nd that a hybrid method combined with the non-iterative method can further improve the convergence rate. To show the efficiency of the presented method we give some numerical examples.

A promising method for removal of Cs ions from water and their incorporation into stable crystal structure ready for safe and permanent disposal was described. Cs-exchanged X zeolite was hot-pressed at temperature ranging from 800 to 950 ℃ to fabricate dense pollucite ceramics. It was found that the application of external pressure reduced the pollucite formation temperature. The effect of sintering temperature on density, phase composition and mechanical properties was investigated. The highest density of 92.5 %TD and the highest compressive strength of 79 MPa were measured in pollucite hot-pressed at 950 ℃ for 3 h. Heterogeneity of samples obtained at 950 ℃ was determined using scanning electron microscopy. The pollucite hot-pressed at 950 ℃ had low linear thermal expansion coefficient of ~4.67 × 10<sup>-6</sup> K<sup>-1</sup> in the temperature range from 100 to 1000 ℃.

Poly(vinyl alcohol)/graphene (PVA/Gr) nanocomposite was synthesized with the aim of developing anovel improved material. The PVA/Gr nanocomposite was characterized by UV–visible spectroscopy,cyclic voltammetry, Raman spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, andX-ray photoelectron spectroscopy analyses, and the interaction of PVA molecules with graphene wasexamined. Introduction of Gr led to improved mechanical and thermal properties of the PVA/Grnanocomposite compared to pure PVA, as well as strong antibacterial activity against the bacterial strainStaphylococcus aureus. The PVA/Gr nanocomposite was non-cytotoxic against healthy peripheral bloodmononuclear cells by MTT assay, indicating its high potential for biomedical applications.

Experience with an On-board Weighing System Solution for Heavy Vehicles
Goran Radoičić,Miomir Jovanović,Miodrag Arsić 한국전자통신연구원 2016 ETRI Journal Vol.38 No.4
Mining, construction, and other special vehicles for heavy use are designed to work under high-performance and off-road working conditions. The driving and executive mechanisms of the support structures and superstructures of these vehicles frequently operate under high loads. Such high loads place the equipment under constant risk of an accident and can jeopardize the dynamic stability of the machinery. An experimental investigation was conducted on a refuse collection vehicle. The aim of this research was to determine the working conditions of a real vehicle: the kinematics of the waste container, that is, a hydraulic rotate drum for waste collection; the dynamics of the load manipulator (superstructure); the vibrations of the vehicle mass; and the strain (stress) of the elements responsible for the supporting structure. For an examination of the force (weight) on the rear axle of a heavy vehicle, caused by its own weight and additional load, a universal measurement system is proposed. As a result of this investigation, we propose an alternative system for continuous vehicle weighing during waste collection while in motion, that is, an on-board weighing system, and provide suggestions for measuring equipment designs.

NiTi alloys are the most technologically important medical Shape Memory Alloys in a wide range of applications used in Orthopaedics, Neurology, Cardiology and interventional Radiology as guide-wires,self-expandable stents, stent grafts, inferior vena cava filters and clinical instruments. This paper discusses the use of rapid solidification by the melt spinning method for the preparation of thin NiTi ribbons for medical uses. Generally, the application of rapid solidification via melt-spinning can change the micro-structure drastically, which improves ductility and shape memory characteristics and leads to samples with small dimensions. As the increase in the wheel speed led to a reduced ribbon thickness, the cooling rate increased and, therefore, the martensitic substructure became finer. Furthermore, no transition from the crystalline phase to the amorphous phase was obtained by increasing the cooling rate, even at a wheel speed of 30 m/s. Specimens for our metallographic investigation were cut from the longitudinal cross sec-tions of melt-spun ribbons. Conventional TEM studies were carried out with an acceleration voltage of 120 kV. Additionally, the chemical composition of the samples was examined with a TEM equipped with an EDX analyser. The crystallographic structure was determined using Bragg-Brentano x-ray diffraction with Cu-Kα radiation at room temperature.

We report the organic synthesis and growth of antimony sulfide (Sb2S3) amorphous nanospheres to nanowires via a simple, colloidal synthetic method. Amorphous Sb2S3 nanospheres self-assembly in wires formation was dispersed in isopropyl alcohol. With increased heating time, Sb2S3 nanospheres grew into Sb2S3nanowires, probably involving both mechanisms of Ostwald-ripening and spherical nanoparticle self-organization through oriented-attachment of individual nanoparticles. Also, the as-synthesized Sb2S3 nanowires with different heating times (0, 5 and 10 min.) from the moment of appearance of the Sb2S3 precipitate were analyzed. The observed nanowires become longer with increased heating time and are around 100nm in diameter and 10-20 μm in length. UV-Vis absorption spectroscopy reveals that the optical band-gap energy of the Sb2S3 nanowires is independent of the heating times and is found to be ~1.5-1.6 eV. The optical band-gap energy found for amorphous Sb2S3 nanospheres was also ~1.5 eV. The structure of Sb2S3samples was refined down to R-factors of 10.82, 11.76 and 12.08%. The refinement showed that Sb2S3powder belongs to the orthorhombic type with space group Pbnm (no. 62) and that Sb2S3 nanowires grow along the [010] direction.

This study discusses the possibility of fabrication of textile nanocomposites with antimicrobial activity againstantibiotics-resistant bacterial strains and yeast. Modification of cotton fabric with oxalic acid solutions of differentconcentrations provided free carboxyl groups for binding of Cu2+-ions from copper (II) sulfate solution which were furtherreduced with sodium borohydride in alkaline solution. An increase in the concentration of applied oxalic acid resulted inlarger amounts of free carboxyl groups on the cotton fibers, Cu2+-ions uptake and total amounts of Cu-based nanoparticlesafter reduction. XPS and XRD analyses suggested that nanoparticles mainly consisted of CuO with fractions of Cu2O. Fabricated textile nanocomposites ensured maximum reduction of Gram-negative E. coli ATCC 25922, E. coli NCTC 13846,E. coli ATCC BAA-2469, K. pneumoniae ATCC-BAA 2146 and P. aeruginosa ATCC 27853, Gram-positive bacteria S. aureus ATCC 25923 and S. aureus ATCC 43300 and yeast C. albicans ATCC 24433. Additionally, controlled release ofCu2+-ions from fabrics into the physiological saline solution was obtained within 24 hours.
